I'm not sure about window-mounted antennas.  I've seen disk 
antennas that should be roof mounted running about $300.  (Think 
something maybe 6" across and about an inch high, very roughly.) 
You need a good view of the sky because you need to be able to see 
at least three GPS satellites to solve for lat/long/time, but any 
additional satellites will give you better accuracy.

100ms still seems high, says the guy who just noticed that I'm 
about a second off.  (But my cable modem was down pretty much all 
day yesterday.)  My numbers are usually in the 10-20 msec range.
